Perfectly possible. We have managed all of DECNET, TCP/IP, XNS and private
protocols, on a mixture of transceiver types, controllers, computers etc.

We have even added in ISO 8802/2 style packets (protocol ID field replaced
by length field).

One main worry is to avoid protocols which make widespread use of broadcast
and multicast packets (i.e. send lots at frequent intervals).
